“…The FT-IR spectra of TiO 2 , DOX-TiO 2, and pure DOX are presented in Figure 4. The bands at 3,425 is attributed to the stretching mode and the "scissor"-bending mode of −OH, respectively, which come from H 2 O absorbed on the surface of the products and −OH on the surface of TiO 2 (Chen et al, 2009). The absorption band at 690 cm −1 is attributed to Ti-O stretching vibration (Chen et al, 2009;Cui M. et al, 2012).…”

The bands at 1641 and 1500 cm −1 may attributed to C O and C-O-C of by products of the reaction as route 1 showed (Ye et al, 2010).…”

By hydrothermal method, porous TiO2 spheres with pompon morphology are successfully synthesized in the tetrabutyl titanate (TBT)–acetic acid (HAc) system with no other additives. The morphological, structural and textural properties of the specimen are figured out by transmission electron microscopy (TEM), scanning electron microscopy (SEM), Fourier Transform Infrared Spectroscopy (FT-IR), X-ray powder diffraction (XRD), N2 adsorption/desorption, and fluorescence microscope. The results show the pompon-like morphology of porous TiO2 with high specific surface area and large pore volume, which can be used as a drug carrier. In this paper, doxorubicin hydrochloride (DOX) is chosen as drug model to understand the process of drug release. And results indicate that the porous TiO2 is biocompatible and can be used for continuing drug-release, which shows lots of possibilities in medical fields.
